AbstractMethodError from SAXParser?

[John Surnow]

I'm seeing the following exception when I attempt the stock quote example:

<Mar 22, 2002 11:45:59 AM PST> <Error> <HTTP> <[WebAppServletContext(4333262,axis)] 
Servlet failed with Exception

I'm using Weblogic 6.0 and crimson.jar. Any ideas as to what could be causing this?

Thanks,

John
